Man-portable nordenfelt gun of the Soviet era that apparently provided 'near minigun' performance by combining the ROF but to be suitable for a soldier to handle. It uses the 7.62x39 round but the ammo supply was limited as the weapon is magazine fed.
The Pribor 3B still worked but was also quite hard to control due to the recoil force, Cartridge ejection is downwards BEHIND the magazine area as the weapon uses a gas/recoil operaton similar to that used in the AN94 Abakan assault rifle currently used by Russian special forces. Another variant of the Pribor-3B was made from AKM smilar parts to ease production. The Pribor-3B would be more practical as a tripod mounted machine gun if its possible to make a belt feed device for it.
